WINDOW CONSTRUCTION.

Application yfiled September 11, 1919. ySerial No. 323,147.

T all 'whom t may concern:

Be it known that I, FRANCIS J. PLYM, a citizen of the United States,residing at Niles, in the county of Ber-rien and State of Michigan, haveinvented new and useful lm- 1 provements in Window Constructions, of

which the following is a specication. j

My invention relates particularly to improvements in the construction ofwindow tracks and associated mechanism, whereby windows may be openedlwith a swinging motion in a vertical plane vand yet may be weathertightwhen closed, and I have sought to improve upon ythe `construction of thetracks, to improve upon the connection of j the slidable elements withthe track, to provide an improved weatherstrip 'for keeping wind andrain from entering between the sash and the frame, to improve in generalupon existing structures of this character, and to accomplish suchfurther objects, advantages, and capabilities as will later more fullyappear. f

With these and other incidental objects in view, l have devised thestructure shown in the accompanying drawings, in which Fig. 1 shows avertical transverse section through an open window showing myconstruction applied.

Fig. 2 is a fragmentary 'elevation of the structure shown in Fig. 1 withpart of the frame broken away and in section.

Fig. 3 is a perspective view of my improved track, showing theconnections betweenthe track and the window sash.

Figs. 4, 5, 6, 7 and 8 are detail cross-sec tions along the lines 4 4,5-5, 6-6, 7 7, and 8-8 of Fig. 2 respectively.

Referring more specifically to these draw* ings, the window casing is.denoted by the numeral 1, the sash by 2, and the track in general by 3.A link 4 is pivotally connected at 'one end to a block 10 secured to theedge of the sash 2, while its opposite end is pivoted at 9 to block 8.Intermediate the ends and nearer tothe one last named is pivoted at 7 alink l5, whose opposite end is piv-v oted at 6 to a block 12 secured vtotrack 3, as best shown in Fig. 6. At its upper edge, sash 2 has securedthereto a metal strip 11,

. which is pivoted at one end to slidable block 11a, which runs inguideway 17 of track 3, shown best in Fig. 3. The details of thisconstruction are shown best in Fig. 4, where metalstrip 11 is shownconnected to block 11a by a rivet 11b, the block being` embossed 14 and15,the former adapted to co-operate with track 3 to form a weathertightconstruction to keep wind and water from entering bet-ween the sash andtrack, and the latter cooperating with window stops 16 to from anotherweather tight connection. The edges 15 enter into a groove or groovesformed within or'betweenl stops 16, and, being resilient, a close fit isnecessarily secured between the parts at this point. Part 14, beingresilient, also, is bent slightly when it comes into contact with track3 to form a tight but yielding joint when the window is closed. It willbe noticed that this weatherstrip not only helps to form watertightjoints with the window stops and track, but furnishes also a resilientmeans to assist in keeping the window from rattling in strong winds.

Referring to Figs. 3 and 4, it will be seen that track 3 comprises ahollow guideway 17, whose edges 18 form overhangs which are bent sharplyoutwardly in extensions 19 and 20, which are then bent away from theface which is to be directed toward the sash, forming rearwardlyextending side pieces 21 and 22. Part 22 is then bent laterally to formthe edge strip 23 provided with holes for the reception of screws bymeans of which the track is fastened to the window frame. This edgestrip 23 has the securing screws covered by window stop pieces 16 tomore securely fasten the track in place and also to hide the screws. Thesheet metal of which track 3 is made is resilient, and therefore yieldsto cause the track to cooperate with part 14 in forming a tight butyielding connection between the sash and the frame.

It is noted that part 21 of track 3 fits closely against the woodenstrip 21 of the window frame, thereby forming a tight joint to preventsnow, rain, or dust from getting between the woodwork and the track.

From this` description it will be seen that grooved track 3 with itsslot facing the sash serves as a guideway for slidable blocks 8 and 11a;that, because of its resiliency, it cooperates with the weatherstrip onthe edge of the sash to keep out wind and rain; also because of itsresiliency, it will help the weatherstrip in compensating' jor swellingand contracting or the sash and frame as the same gets wet and driesout, and also beV cause of its resiliency, .a.,.closev but sufficientlyyielding connection between the sash and frame is formed to avoid yanystraining of parts when opening and closing the window.

In operation, when the sash is pushed outwardly at the bottom, itcarries withitpthe upper end or link Ll, and because ofthe'pivotalc'onnectionvof link 5 at points 6 and 7, the lower end of link lis caused to move upwardly, carrying with it, in guideway 17, the 4block8. At the same time, the upper edge 4of the sash attached t block 1lL1moves downwardly, carrying said yblock downwardly along gl'iideway 17.The operation ofthe device is very much improved by having the hollowtrack and the blocks or shoes ruiming in the openingl or' the track.

It should be noted that thisdevice vmay i beinstalledbyattachingb'lockl() 'and'.str'ip ll tothe edge of the sash and thenplacingthis whole assembly in place within'the window trame, after whichscrews are inserted, the holes in the edge strip 23 or' track 3 landwindow stops `16 are put on to nishthe installation. This method ofassembly and Iinstallation is much simpler thanprevious methods andmakes it possible for the work to be done quickly and easily.

Though I have shown and described in considerable ldetail the preferredform of my invention, this is not to be construed in a limitingpsense,the `same being done for the purpose of enabling one 'skilled in the artto which this invention pertains to construct and irs-eth1; same.

Having now described my invention,

l claim: t
